It's a pretty reasonable thought if you ask me. This is a product from a company that is willing to include adwares to their "free" software to generate revenue. I am not saying it's wrong. It is perfectly fine because they need to make money. Thank you for making it simple. And thank you for giving me motivation to code similar work.

And if Obama says NSA doesn't spy on Americans, would you also believe that? You seem to misunderstand something. All rights currently belong to BitTorrent Inc. because it is not under open source license. As a person who uses this for their private data, you should be looking at every possiblity of being "the product"; if you are not paying for it, you are the product. Who knows what kind of backdoors this thing could have. I was actually surprised that they were collecting some info like the sizes of data being synced. You just said how competition works. That's right. People would just switch over to the better alternative. That is exactly why this is not open source, they want no alternative. They don't want people to fork it and code a better one. If it's just updates you're concern, one can just add notification if they were running an old version, or even add auto-update capabilities.

A pity because the licensing of this application goes against its very nature -- decentralization, distributed. The reason why BitTorrent Inc licensed it under proprietary is simply because they want to profit from it. They want no competitor forking similar product. They are a company, it would be stupid for a for-profit organization to give something for free without anything in return. Plain and simple. BitTorrent Inc have never released any open source software. So they said they "might" open source it? No, they wont. It's for press. But no worries. The idea itself is simple. Just be patient and wait for someone to code a geniune community-driven BitTorrent Sync program.

Due to the nature of this application, it's probably not possible. First, it's decentralized, so there is no central place to "register" or "login". Second, it's not wise to generate secrets based on email and password as supplementary.

In terms of probability, the likelihood of your PC or laptop getting stolen is probably higher than someone generating the same secret.
